STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 794,622, dated July 11,1905,

Application tiled December 22, 1903. Serial No. 186,150.

T0 all whom t may concern:

Be it known that we, J 00K BEDELL HENDER- SON and JocK LEE HENDERSON,citizens of the United. States, residing at Williamstown, in the countyof Wood and State of West Virginia, have invented new and usefulImprovements in Station-Indicators, of which the following is aspecification.

Our invention relates to improvements in station-indicators, andpertains more particularly to that class used on street and railway carsand which are operated by hand by the conductor.

The object of our invention is to provide an indicator which willindicate the dierent streets or stations and after the car has traveledto the end of the route will start and indicate in their proper orderthe streets or stations over the line on the return trip of the car, andthus we aim to produce a more simple, cheap, and effective indicatorthan has heretofore been produced.

In the accompanying drawings, Figure 1 is a side view of our improvedindicator, showing the side of the casing removed. Fig. 2 is a top planview showing the winding-drum and the belt-operating drum. Fig. 3 is avertical sectional view taken on the line m x of Fig. 2.

Referring now to the drawings, A represents a casing, which may be ofany desired form, but preferably of that shown in the drawings, and thecasing is adapted to be placed in the forward end of the car, where itcan be readily seen by all in the car. The said casing A has in itsforward end an openinga, which extends transverse the casing and throughwhich the belt is adapted to be exhibited, and the same is preferablycovered by a glass plate A', and thus dirt and moisture are preventedfrom entering the same. Adjacent the rear end of said casing andextending horizontally transversely thereof are two shafts B and B',which are arranged one above the other and a considerable distanceapart. The said shafts are rigidly supported by the side of the casingand are therefore held against rotation, for the purpose hereinaftermore fully described. Rotatably mounted upon said shafts B and B are thedrums O and O', and said drums are of a diameter considerably largerthan that of the shafts, thus leaving an enlarged space between thesame; Coiled upon the shaft B within the drum C is a coil-spring D,which has one end secured to the shaft B and the other secured to thedrum C, and thus we produce a spring-drum the purpose and operation ofwhich will be hereinafter more fully described. The shaft B has a coiledspring Dl mounted therein within the drum O and secured in the samemanner as the spring D, and the operation is therefore the same.

The drums O and C' are provided at their ends with outwardly extendingcircular flanges O2 and O3, which serve as guides for the belt, thuscausing the same to be evenly wound on the drums and also preventing thesame from slipping therefrom.

Rotatably mounted in the forward end of the frame A is an enlarged maindrive-drum E, which has its outer circumference in a line with the outeredge of the drum O. The said drum E is carried by a shaft E', which isrotatably mounted in the frame, and one end of said shaft extendsthrough the casing A and is squared at e for the purpose of receiving akey by means of which the main drive-drum may be driven independent ofthe mechanism hereinafter described, and thus the belt is positively andmore rapidly driven when desired. It will be understood that the pitchof the worm-gear H is such that the worm J may be driven thereby, butthe other mechanism being thrown out of engagement With the shaft, asheretofore described. rIhe said drum E adjacent each end is providedwith a row of circumferentiallyarranged outwardly-extending teeth E',and

passing over said drum is a belt F, which carries at each side andsecured thereto the metal tapes F', which are provided with openings f,Which are adapted to receive the teeth c', carried by the drum E, andthus the belt is driven. The said belt F has printed or painted thereonthe diiferent streets. The shaft E within the frame has rigidly mountedthereon a gear H, the purpose of which is to drive said shaft, ashereinafter more fully described.

Mounted in said frame below the drum E is a small idle drum I, whichcauses the belt F to travel in a vertical plane across the opening a,and thus the name or number of the street is plainly exhibited to thepassengers in the car.

The tendency of the springs D and D', carried by the drums C and C', isto hold or turn the drum in the direction indicated by arrows in Fig. l.The belt F has its ends secured to the drums C and C', as clearly shownin Fig. 3, and passes over the drum E and the small drum I, and the twoends of the belt being normally drawn tight by the springs in the drumsC and C' the belt is at all times held tightly over the drums E and I.

The sprocket-wheel H, carried by the drum E, has meshing therewith ahorizontal worm J, which is rigidly supported upon the elongatedhorizontal shaft J', which is rotatably mounted in the frame A in anydesired manner. The said shaft J extends across the face of avertically-disposed rotatable disk K, which has the teeth le, carried bythe outer side thereof. The shaft J' carries two small bevel-gears L andL', which mesh with the teeth 7c on opposite sides of the disk K, andthus the shaft J' may be rotated in either direction. The gears L and L'are loosely mounted upon the shaft J', but held against longitudinalmovement, and thus the gears are at all times in mesh with and revolvedby the large gear K, and mounted upon said shaft J between the gears Land L' is a clutch mechanism M, which is slidable upon said shaft,yetkeyed thereto, so as to at all times revolve therewith, and theclutch mechanism is adapted to be driven in either direction by thegears L and L', and thus the shaft J is driven in either direction.Pivoted Within the casing A is a lever N, the inner end of which isbifurcated at n and is adapted to enter a circumferential groove m inthe clutch M, and thus the shaft is readily connected with either of thegears L and L'. The said disk K has its outer periphery provided withratchet-teeth O,`and pivoted upon the same shaft K', carrying the diskK, is a lever P, which has a pawl T, which is adapted to engage saidteeth O and is held against said teeth by the spring t, and a spring onormally holds the lever in an upward position.

The operation of our device is as follows:

The downward pull of the lever P causes the` pawl to turn the disk K adistance suflcient .to cause the shaft J' to be revolved through themedium of the gear L, and thus the belt F is caused to revolve inadirection indicated by the arrowon the drum C2 in Fig. 1, and said belttravels a distance sufficient to cause another sign to be exhibitedthrough the opening a. The slack of the belt between the drum E and thedrum C is taken up by the tension of the springs within the drums. Whenthe end of the route is reached, the belt has been wound upon the drumC, and by throwing the clutch M into engagement with the gear L' thedrum E is caused to revolve in the opposite direction, and the belt F isdrawn from the drum C and wound-by thel spring upon the drum C'.

The lower face of the casing A is provided 4 the belt, a worm-gearcarried bysaid drum,

a shaft adjacent said worm-gear, a worm carried by said shaft andmeshing with the wormgear, a large beveled gear adjacent the oppositeend of said shaft, beveled gears rotatably mounted upon said shaft andmeshing with opposite sides of said beveled gear and held againstlongitudinal movement upon the shaft, a clutch slidably mounted on saidshaft between the gears and held against rotation, said clutch having areduced central portion and an intermediately-pivoted lever having itsupper end bifurcated and resting in said reduced central portion of theclutch, means for holding the lower end of said lever in its adjustedposition, the outer periphery of said large beveled gear havingratchet-teeth, a lever pivoted on the shaft of said large gear, a pawlcarried by the lever and normally held in engagement with theratchet-teeth carried by the large beveled gear, and means for normallyholding the lever in an upward position.

A station-indicator, comprising a belt, a drum over which said beltpasses, a wormgear carried by said drum, a worm meshing with saidworm-gear, and adapted to drive the worm-gear in either direction, andmeans carried by the opposite end of the drum for rotating it in eitherdirection independent of the worm, the pitch of the worm and worm-gearbeing such that the worm can be driven by said worm-gear.
